Description

Headrest putting on and taking off structure

The present invention relates to a headrest detachable structure, and more particularly, to a headrest detachable structure for installing a head pusher on the side of the headrest so as to be pushed inward and detached from the seat back so as to improve operability when detaching the headrest. .

Automobile seats have front and rear seats, the front seats have a separate type, and the rear seats are generally bench type. An example of a bench seat is shown in FIG. 1, but the adjustment lever 7 is provided in the lower part of the seat cushion 1, and the position of the seat cushion 1 can be adjusted back and forth.

In addition, the head rest 10 is installed at the upper portion of the seat back 5 for the safety of the crash and the convenience of the rider.

Here, the conventional removal structure of the head rest is fixed to the top of the seat back 5, as shown in Figure 2, the stay 8 is formed with a locking groove (8a) on the side, the head is inserted into the stay (8) The rest guide 12, the lever 14 is attached to one side edge of the head rest guide 12 and folds in one direction, and the locking groove 8a of the stay 8, and the lever ( It is composed of a spring-type fastener 16 which is moved back and forth in accordance with the operation of 14, and a support 18 for supporting the end of the spring-type fastener 16 to the headrest guide 12.

The conventional head rest detachment structure configured as described above has a lever 14 positioned at one side of the head rest guide 12 in order to separate the head rest 10 from the stay 8 fixed to the seat back 5. You can flip it.

That is, when the lever 14 is flipped to the rear of the head rest guide 12, the spring-type fastener 16 fixed thereto is separated from the catching groove 8 a of the stay 8, in which case the head rest guide What is necessary is just to pull out 12 from the stay 8 of the seat back 5 upwards.

Of course, in order to attach the headrest 10 to the seat back 5, it is good to proceed in the reverse order of removal as mentioned above.

However, the headrest detachment structure as described above is detached by flipping the lever 14 protruding from one side of the headrest guide 12 to the rear so that the appearance of the headrest 10 is not only degraded, but also the operability of the headrest detachment is inferior. There is a problem.

The present invention was devised to solve the above problems, and when the head pusher is pushed inward from the side of the head rest guide, the head rest can be detached from the seat back so that the assembly of the head rest is easy as well as the appearance. And a headrest attachment and detachment structure in which operability is also improved.

50: seat back 52: stay

52a: locking groove 60: head rest

62: Head Rest Guide 64: Head Pusher

66: latch opening 66a: square hole

68: return spring

The headrest detachment structure of the present invention for realizing the above object is a stay fixed to the top of the seat back and the engaging groove is formed on the side, and the headrest guide of the headrest formed with a hole in the middle so that the top of the stay is inserted; The head pusher coupled to the side of the head rest guide and moved in the direction of the head rest guide by an external force, and the one side of the square hole is inserted into the locking groove of the stay and is operated by the head pusher. And a return spring that is linearly moved along with the return spring, which is supported inside the head rest guide and positioned at the end of the latch to provide elastic force to the latch.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

Head restraint structure according to the present invention is fixed to the upper end of the seat back 50, as shown in Figure 3 and the stay groove 52a is formed on the side, and the upper end of the stay 52 is inserted The head rest guide 62 of the head rest 60 having a hole 62a formed in the middle thereof, and coupled to the side of the head rest guide 62 and moved in the direction of the head rest guide 62 by an external force. Inherent in the head pusher 64 and the head rest guide 62, one side of the square hole 66a is inserted into the locking groove 52a of the stay 52, and is straight along the operation of the head pusher 64. And a return spring 68 which is supported on the inside of the headrest guide 62 and is positioned at the end of the stopper 66 to provide elastic force to the stopper 66. .

Here, the head rest guide 62 is formed with a groove 62b in the 'b' shape so that the head pusher 64 is located on the side thereof, the head pusher 64 is the head rest guide ( The insertion part 64a is formed so that the side of 62 may be inserted inside a head rest guide.

In addition, one end of the locking hole 66 is bent upwardly and fixed to the head pusher 64, and a guide hole 66b is formed at the other end thereof, and the stay 52 passes through the locking groove. A square hole 66a is formed to catch the 52a, and the return spring 68 is formed in a plate-belt shape in which both ends are bent backwards, and is supported on the inner side of the head rest guide 62, and the front surface of the latch is closed. It is in close contact so as to push one end of the sphere 66.

Referring to the operation of the headrest detachable structure according to the present invention configured as described above are as follows.

In order to remove the head rest 60 fixed to the stay 52 of the seat back 50, when the head pusher 64 is pushed toward the head rest guide 62 side, the insertion portion 64a of the head pusher 64 becomes the head. The inside of the rest guide 62 enters, and the head pusher 64 causes the locking hole 66 to compress the return spring 68 while the square hole 66a on the inner side thereof engages the locking groove 52a of the stay 52. ).

At this time. The headrest 60 can be removed by lifting the headrest 60 upward from the stay 52 of the seat back 50.

On the contrary, in order to mount the head rest 60 to the seat back 50, while the head pusher 64 is pressed, the head rest guide 62 is inserted into the stay 52 and the head pusher 64 is released. The locking mechanism 66 moves together with the head pusher 64 by the spring force of the spring 68 to enter the locking groove 52a of the stay 52. Thus, the head rest 60 is fixed to the stay 52 of the seat back 50.

The headrest detachment structure according to the present invention, which is constructed and acts as described above, allows the head pusher 64 to move in and outward from the side of the headrest guide 62 to remove the headrest 60 from the seat back 50. Since it is possible to do not only the assembly structure is easy, but also has the advantage that the appearance and marketability is improved.
